1 SCHEME OF TESTING AND INSPECTION FOR CERTIFICATION OF CROSSLINKED POLYETHYLENE INSULATED THERMOPLASTIC SHEATHED CABLES FOR WORKING VOLTAGES UPTO AND INCLUDING 1100 VOLTS ACCORDING TO IS 7098(Part 1):1988 (Including Amendment Nos.1 to 3) 1. LABORATORY A laboratory shall be maintained which shall be suitably equipped and staffed, where different tests given in the specification shall be carried out in accordance with the methods given in the specification. 1.1 All testing apparatus shall be periodically checked and calibrated records of such checks/calibration shall be maintained. 2. TEST RECORDS - All records of tests and inspection shall be kept in suitable forms approved by the Bureau. 2.1 Copies of any records and other connected papers that may be required by the Bureau shall be made available at any time on request. 3. QUALITY CONTROL It is recommended that, as far as possible, Statistical Quality Control (SQC) methods may be used for controlling the quality of the product during production as envisaged in this Scheme [See IS 397(Part I):2003 to IS 397 (Part 4):2003]. 3.1 In addition, effort should be made to gradually introduce Quality Management system in accordance with IS/ISO 9001: STANDARD MARK The Standard Mark, as given in Column (1) of the First Schedule of the licence, shall be stenciled on the drum along with other information about the cable; provided always that each length of the cable wound on the drum conforms to every requirement of the specification. 4.1 OTHER MARKINGS - In addition the cable shall carry the information according to clause 18.2 of IS 7098(Part 1) either stenciled on the drum or contained in a label attached to it, and also the identification in code or otherwise to enable the date and lot manufacture to be traced back to factory records. 1

2 4.2 The manufacturer s identification and cable identification shall be done as per clause 17.1 and 17.2 of IS 7098(Part 1). 4.3 The Standard Mark shall be applied on the label or a tag, in such a manner, that as far as possible, it gets destroyed when the drums are opened for using the cable, as other wise it may be fraudulently used by any person so as to deceive the consumers. 4.4 The cut ends of the cable shall be sealed by means of non-hygroscopic sealing materials. 5. LEVELS OF CONTROL - The tests, as indicated in Table 1 attached and at the levels of control specified therein, shall be carried out on the whole production of the factory which is covered by this scheme and appropriate records and charts maintained in accordance with paragraph 2 above. All the production which conforms to the Indian Standards and covered by the licence shall be marked with certification mark of the Bureau. 5.1 On the basis of test and inspection results, the decision regarding conformity or otherwise of the cables to the requirements of the specification shall be taken as given in remarks column of Table In respect of all other clauses of the specification the factory will maintain appropriate control and checks to ensure that their product conforms to the various requirements of this specification. 6. MATERIALS - The Various raw material used in the manufacturer of cables shall conform to the various requirements as given in section 2 of IS 7098(Pt.1). 7. REJECTIONS - A separate record shall be maintained giving information relating to the rejection of the production not conforming to the requirements of the specification and the method of its disposal. Such material shall in no circumstances be stored together with those conforming to the specification. 8. SAMPLES - The licensee shall supply, free of charge, the samples required in accordance with the Bureau of Indian Standards (Certification) Regulations, 1988, as subsequently amended, from the factory or godowns. The Bureau shall pay for the samples taken by it from the open market. 2

3 9. REPLACEMENT- whenever a complaint is received soon after the goods with Standard marks have been purchased and used, and if there is adequate evidence that the goods have not been misused, defective goods are replaced free of cost by the licensee in case the complaint is proved to be genuine and the warranty period (where applicable) has not expired. The final authority to judge the conformity of the product to the Indian Standard shall be with the Bureau. The firm shall have own complaint investigation system as per IS/ISO In the event of any damages caused by the goods bearing the standard Marks, or claim being filed by the consumers against BIS Standard mark and not conforming to the relevant Indian Standard, entire liability arising out of such non conforming product shall be of licensee and BIS shall not in any way be responsible in such cases. 10. STOP MARKING - The marking of the product shall be stopped under intimation to the Bureau if, at any time, there is some difficulty in maintaining the conformity of their product to the specification, or the testing equipment goes out of order. The marking may be resumed as soon as the defects are removed under intimation to Bureau The marking of the product shall be stopped immediately if directed to do so by Bureau for any reason. The marking may then be resumed only after permission by the Bureau. The information regarding resumption of marking shall also be sent to the Bureau. 11. PRODUCTION DATA -The licensee shall send to BIS as per the enclosed proforma- 1 to be authenticated by a Chartered Accountant a statement of quantity produced, marked and exported by him and the trade value thereof at the end of each operative year of the licence..
